Nigeria: BUA Cement plans to use loans worth US$500m towards the construction of two new 3Mt/yr cement plants in Sokoto State. When operational, the new plants will increase the producer's installed capacity by 55% to 17Mt/yr. Local press has reported that BUA Cement plans to run both cement plants using solar power, and to produce cement using alternative fuel (AF). Additionally, the producer will use a portion of the funding to replace part of its diesel-fuelled cement truck fleet with new natural gas-fuelled models.
Of a total US$500m in financing secured by BUA Cement on 5 June 2023, the International Finance Corporation (IFC) lent US$161m (32%) and African Development Bank, Africa Finance Corporation and the German Investment Corporation jointly lent US$245m (49%), with the remainder advanced by institutional investors.
France: Hoffmann Green Cement Technologies has commissioned its H2 plant, a 1000t/day clinker-free cement plant, adjacent to its existing H1 clinker-free cement plant in Bournezeau, Pays de la Loire. L'Usine Nouvelle News has reported that the new plant took 24 months to build and cost Euro22m. The main part of the plant consists of a 70m tower, where activated clay, ground granulated blast furnace slag (GGBFS) and gypsum are mixed to produce the cement. It is installed with solar panels capable of supplying 50% of its energy consumption. The producer says that its clinker-free cement has over 90% lower CO2 emissions than cement produced with ordinary Portland cement (OPC). It aims to sell 24,000t of the product throughout 2023.
Pakistan: Lucky Cement’s sales totalled US$1.2bn during the first nine months of the 2023 financial year, a rise of 28% year-on-year from US$941m during the corresponding period in the 2022 financial year. The Balochistan Times newspaper has reported that Lucky Cement attributed the growth to the commencement of operations of its new subsidiary, utilities provider Lucky Electric Power. The company increased its profit after tax by 83%, to US$172m.
Lucky Cement commissioned its Pezu cement plant’s new Line 2 at the end of the second quarter of the 2023 financial year. This increased the company’s installed production capacity by 26% to 15.3Mt/yr. The producer also inaugurated a new 34MW solar power plant, and completed negotiations for another, 25MW, solar power plant at its Karachi cement plant. The latest solar power plant is scheduled for commissioning later in 2023.
US: Holcim US has joined the Department of Energy's (DOE) 'Better Climate Challenge' to reduce CO2 emissions and save energy. It is the first cement producer to commit to the DOE program. The subsidiary of Switzerland-based Holcim plans to power the electrical operations at 13 cement plants in the country with 100% renewable energy by 2030 and to reach net zero CO2 emissions by 2050. As part of the 'Better Climate Challenge' it has committed to reduce CO2 emissions in the US by at least 25% by 2033.
Examples of current renewable power usage at Holcim US cement plants include the installation of three onsite wind turbines at the Paulding plant in Ohio that generate 11,500MWh while a forthcoming solar unit at the Hagerstown plant in Maryland will generate up to 18,440MWh. All 13 Holcim cement plants will conduct reviews to identify projects that could contribute to meeting goals of the challenge.
With grant support from the DOE, Holcim is also investigating the feasibility of using carbon capture utilisation and storage (CCUS) at its cement plants in Portland, Colorado, and Ste. Genevieve, Missouri. In addition to involvement in the Better Climate Challenge, Holcim US is a continuing partner of the DOE's 'Better Plants Challenge', sharing facility-level energy data and solutions to help guide other industrial companies with implementing energy solutions in their facilities.
India: Udaipur Cement Works has commissioned a 1MWp floating solar unit at its Dabok mine in Rajasthan. The project was supplied by Oriana Power, according to the Press Trust of India. Udaipur Cement Works is a subsidiary of JK Lakshmi Cement.
Anirudh Saraswat, the co-founder and chief business officer of Oriana Power, said "The state has vast untapped potential in terms of intense solar radiation, one of the highest numbers of sunny days in a year and availability of vast barren and uncultivable, unutilised government and private land. This has the potential to make Rajasthan a highly preferred destination for solar energy at the global level."
Oriana Power is an India-based solar energy products provider that finances, constructs and operates solar projects for industrial and commercial customers.
Bestway Cement inaugurates Mianwali cement plant
30 March 2023Pakistan: Bestway Cement has ignited the kiln of Line 1 of its Mianwali cement plant in Punjab. The line has a capacity of 2.3Mt/yr. The Pakistan Observer newspaper has reported that it increases the producer's cement capacity by 18% to 15.3Mt/yr and brings its total number of production lines to eight. The Mianwali cement plant is equipped with a 20MW solar power plant and will run on 50% renewable energy. It also has a 9MW waste heat recovery (WHR) plant, an air cooled condenser (ACC) system and a rainwater harvesting system.
Bestway Cement CEO Lord Zameer Choudrey said "It's a great day for the company. Our new greenfield production line at Mianwali has been set up in a record time, despite various hurdles and supply chain disruptions caused by Covid-19."
China: Anhui Conch’s sales fell by 21% year-on-year to US$19.2bn in 2022 from US$24.4bn in 2021. Its net profit dropped by 52% to US$2.31bn from US$4.84bn. Sales volumes of cement and clinker decreased by 24% to 310Mt. It blamed the situation on weakening market demand and high energy costs.
New projects that started operation in 2022 included a capacity replacement scheme at its Anhui Chizhou Conch Cement subsidiary and two new clinker production lines at the Qarshi project in Uzbekistan. The group also completed its acquisition of Chongqing Duoji Renewable Resources, Naimanqi Hongji Cement and Chifeng Hahe Cement. By the end of 2022 its cement and concrete production capacities rose by 1% to 269Mt and 73% to 25.5Mm3. Its solar power capacity also more than doubled to 475MW.
Poland: Lafarge Polska has signed a 10-year power supply agreement with Germany-based energy provider RWE Supply & Trading. Under the contract, Lafarge Polska will receive renewable energy from Windfarm Polska III on the coast at Sztum, Pomeranian Voivodeship. It is owned by German state-owned Stadtwerke München (SWM).
Renewables Now News has reported that Lafarge Polska is currently building a 41MW solar power plant at the site of its former Wierzbica cement plant in Masovian Voivodeship. This will cover a further 10% of its energy consumption.
US: Holcim US has appointed TotalEnergies to install, maintain and operate a 33MW solar power plant and 38.5MWh battery system at its Florence, Colorado cement plant. By storing energy with the battery system, the plant can relieve demand on the grid at peak times. Holcim will receive roughly 71,000MWh/yr of renewable energy under a minimum 15-year power purchase and storage services agreement (PPSSA). The partners expect the new systems to reduce the plant's CO2 emissions by 40,000t/yr and its energy consumption by 40%.
Holcim North America’s vice president for procurement Atl Martinez said "As we work to accelerate green growth across the US, it's critical that we come to the table with partners who share similar goals around circularity and renewable energy. This initiative with TotalEnergies demonstrates an ongoing determination to transform our operations and lower our carbon footprint. It's a milestone investment that will decrease our reliance on other sources of energy and shrink our utility costs through a powerful combination of clean energy and efficient operations."
